What Does an Alternator Do?

All gasoline-powered vehicles have an alternator. It’s a vital component of your vehicle, and your car, truck, or SUV won’t operate on your drives in Loveland without an alternator that works properly. What does an alternator do? Find out with our guide from the service team at Beechmont Toyota.

What Does an Alternator Do in Your Vehicle?

The alternator recharges your vehicle’s 12-volt battery while the engine is running. Without it, the battery would be drained of its power and your car would not be able to start.

Think of an alternator as a miniature electrical turbine. Utility companies produce electricity when a turbine spins in the presence of an electromagnetic field. Then, a circuit moves the electricity generated from this motion. 

The inner part of the alternator spins when the serpentine belt moves while the engine is running. The alternator then channels this energy into the 12-volt battery. The electrical energy stored in the battery runs the electronic accessories in your vehicle. 

How Long Do Alternators Last?

Most alternators last for 7 to 10 years. Once an alternator dies, you’ll have to replace it with a new or refurbished one. A reliable service center in the Mason-area, like our service center in Cincinnati, can install an alternator when you need it. 

How Much is an Alternator? 

A brand-new alternator typically costs $500 to $1,000. Another option is a remanufactured alternator that costs less, around the $300 to $500 range. 

The best solution is to purchase an OEM part for your new alternator. It’s made specifically for your vehicle, and a new alternator direct from the manufacturer can keep your car, truck, or SUV running in great shape for many years.
